We can for 24 Hours of Daytona & the 24 Hours of Le Mans make 3 races (long) to simulate day>night>day.
Start the first heat (daylight race) with the trackGT ini without fog (night) settings. After exporting
the results for determining the winner by aggregate ( I will explain a little later) adjust the GPL Fog Tool
to add night to the 2nd heat.(One might need to adjust the dlong_speed_adj_coeff setting in the night track ini
to slow the ai if the player is slower in the night version). After the 2nd heat (night race) export again the results
to save for figuring the outcome.
While resting in the bunkhouse as your co-driver does his stint use the GPL Fog Tool to remove the night setting and
if needed readjust the dlong to it's original setting to speed ai up for the daylight final heat race.After completion,
export these results. To figure out the overall results for the 3 heats one can use a program such as Excel to make
a tabulation sheet. Example :spreadsheet.JPG114.14K99 downloads

For 12 Hrs of Sebring , a combination of 3 (day>day>night) Intermediate or pro short races would be half of the 24 hr
races descibed above.

EDIT : See post #6 for further options of 1 time qualifying & retiring ai opponents from further heats.

Perhaps some savvy individual with good knowledge of Excel can come up with a better formulation
template.

Yes, Lee's weather patch will add even more immersion to Endurance racing in GPL.

Thank you again for this amazing discovery using GPL Fog !

Michkov,

Thank you for your suggestion, I was originally aiming for that type of tabulation, but could not find it in my
outdated Microsoft Office Excel 2007. After many minutes of experimenting I came across the AutoSum>average format
and called it good. My GPL rig is old & has limited free space so I am content with this for now, unless someone can
suggest/point me to a different formula/function I can use in Excel 2007.

@ Michel. thank you for bringing up the fact that we can add realism to these races !

As Greg suggested in the GPL Fog topic, Daytona can be a little more realistic looking with the night settings at
less density. I offer two choices to review that I thought were practical. They are still lighter then Greg's suggestion
of 5.0 (500), so some of you might like that better.

3.5 or 350 : This setting to me is very similar to the current Rolex/Nascar night racing we see now. Most evident
in the pitlane view :pits.JPG78.12K46 downloadsinfield.JPG69.55K49 downloadsfront stretch.JPG84.48K43 downloads
The pits do not look like they are having a power outage as at Le Mans when you drive past.

The difference can be seen in the pitlane view and is more subtle in the other two screenies. But in game
the infield & backstretch appear darker. I'm sure some of you will have your own preferences & I would
love to hear them.

And to avoid having to qualify more then once, save your practice results and exit out of GPL.
Now the player can go into his "players" subfolder of your main GPL install and backup/copy the .svg file for the race (eg. dayto24h.svg)
After the first race is complete and your results exported for tabulation, rename the svg file and back it up again for the final (3rd) race.
Now you can run the 2nd stint without having to re-qualify.After the 2nd stint has been completed and results saved, once
again rename the .svg file to complete the final race.

But if you want to add the realism of ai retirements this will not work. The only way to eliminate the retired ai from further races in the series
is to remove them from the driver ini ( be sure to backup/copy before). So if Phil Hill is retired in the 2nd race you will edit the ini to make him not appear in the 3rd heat. Don't forget to edit the drivers following the removed driver eg.[driver #] to make the rest appear in the race.
This choice will mean you will have to qualify (run practice session) before the next race.

So in other words 2 options> : 1 time only qualify = no simulated retirements of ai will be allowed.
simulated retirements = running practices sessions before all races will be required.

I'd suggest to have four drivers in a team, and best three results would count. This might help if someone suffer a disconnection or other technical difficulties.

This would allow to race 4 teams/16 drivers - maybe 5/20. Based on my bandwidth theoratically I can host a full grid event but never tried

No points given. Race laps and race times add up, most laps and least time wins.

Team mates must use the same chassis all along the four rounds. If it would go Chaparral only, we might bend the realism more and specify car usage to three marquee per team.

I’ve always wondered what a realistic mid-60s era Endurance race online simulation would be like in GPL. If VROC is used where multiple classes is allowed and using the Advanced Trainer option in GEM, we could have car classes which replicate old races where our lap times range from: 3:28 (GT Ferrari 330/P4 -top speed 213 mph) to 3:49 (AT GT Ferrari 330/P4 - top speed 169 mph) or a 110% difference.

With those classes, the fastest GT cars would pass the slowest in 11 laps, roughly. In a one hour event, the Standard cars would do 18 laps while the slower ATs would do 16. The faster cars would pass the whole field of slowest cars at least once. The closing speeds might be as high as 44 mph, which would be very interesting. In the 1967 Spa 1000 km race, the lap times varied from 4:22 (Mirage M1) to 5:58 (Matra Djet 5S) over the full race or a 137% difference.

I’m not sure if many people would be interested in driving a slow car versus the fast cars though, but possibly over the races everyone could drive in each class.

The procedure is simply to select the car and class that you’d be driving in GEM and join VROC through GEM. In VROC, you’d select “default” class and team in the join window. Or use Multiplayer through GPL using the server IP address.

So now for the fun part, delete the blank lines and header line expect the topmost.

Select all values in the first 3 columns (NAME, LAPS, TIME)

Go to the Insert tab 2nd item from the left, top of the window.

There select Pivot Table

OK the window

Check all three boxes on the right and you should get a line for each unique name**

Sort by Time than by Laps, both descending and you are done.

I tested this in a German version of Excel 07. Apart from the previously mentioned comma for period difference, functions are named differently. But AFAIK there are no functions in this so that should be no problem.

Questions, confused? Just post below and I'll be around and try to solve the issue.

* If your version of Excel uses commas instead of periodes as decimal mark. And there is no way of changing that except ramming more money down Microsofts throat. ** IMPORTANT if you got drivers using different names in different races (ie Michkov65 & MIchkov67) you have to change the names manually. Else they show up as 2 separate drivers in the Pivottable.
